Another successful OpenBSD setup
I’ve been buying these little boxes from AliExpress for years to use as firewalls and routers. My oldest one is almost 9 years old now! OpenBSD installs just fine. Just a BIOS tweak to always boot up after power is restored.
They do make managed switches, but just to be completely clear, my comment was mostly hyperbole. I just found the general combination of security - mindedness and cheap Chinese hardware curious / amusing.
